HAY-PRESS.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed March 26, 1906. Serial No. 308,171.

To all whom it may concern:

Be it known that I, ELZEAR DORE, a subject of the King of England, residing at Laprairie, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Hay-Presses, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and constructthe same.

This invention relates to new and useful improvements in hay-presses, the object of which is to render more certain the operation of the press, to expedite pressing the hay, and to produce a simple, convenient, and economical machine for the required purpose, which may be produced for a minimum sum, which may be readily set up and connected for use in the field or other location for use, and which may be operated with a minimum power, all as hereinafter more fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, in which similar characters of reference denote like parts in all the views, Figure 1 is a side elevation of the feed end of the machine with the discharge-end portion broken away, as there are no novel features in that portion of the machine. Fig. 2 is a longitudinal vertical sectional view taken approximately centrally through that part of the machine shown in Fig. 1 with the operative parts of the machine shown in full and in dotted positions. Fig. 3 is an end elevational view looking from the left-hand side of Fig. 1. Fig. 4 is a transverse sectional view taken on line 4 4 of Fig. 1, as indicated by the arrow. Fig. 5 is a plan view of driving means adapted to be used in operating the machine. Fig. 6 is a partial side elevational view and a partial sectional view of said driving means. Fig. 7 is a detached plan view of the bifurcated head 6.

Referring first to the press, 1 is the main frame, containing the usual compressionchamber, with fiat springs 2 placed to extend into said chamber, for well understood purposes, through slots cut in the wall of said compression-chamber.

3 is the plunger, which is provided on its outer face with the casting 4, in which is pivotally mounted the end of a plunger-rod 5, which rod is seated at its opposite end in the open end of a head 6, as shown in Figs. 1 and 2, the said head being bifurcated and carrying near the free end of the bifurcated portion a roller 7.

To the frame 1 are secured plates 8, through perforations in which are passed the shaft 9, on which is mounted the rockable lever 10, which, as will be noted, is provided with a slot 11, extending longitudinally thereof and in which rides the roller 7. Connected at one end with the lever 10 and at the opposite end with the head 6 is a link 12, which is free to turn on its pivotal supports and travel with the said lever, as shown in the various positions illustrated in Fig. 2; but owing to the fact that this link is formed of metal or other rigid material the link serves as a support for the head and roller and holds the roller in proper position in said slot. Connected with the lower end of the lever is a rod 13, the opposite end of this rod being held in the bifurcated portion 14 of the arm 15.. This arm 15 is mounted on the vertical spindle 16 and ex: tends, as shown in Figs. 5 and 6, into the path of the rollers 1.7, which depend from the rotatable member 18, mounted on the vertical spindle 19, while the conventional sweep 20f is connected with this member 18 to cause rotation thereof, preferably by animal-power, through said sweep.

As the arm 15 is free to rotate on it spindle,it is evident that rotation of the member 18 will bring the rol ers 17 into contact therewith and carry said arm to the position shown in dotted lines in Fig. 5, thus drawing on the rod 13, rocking the lever 10, and causing the upper end thereof to bear on the outer end of the plunger-rod and forcing the plunger into the compression-chamber, as shown in dotted lines in Fig. 2.

When the plunger has reached its limit of inward movement, the roller 17 is about to pass beyond the range of the arm 15, and when said roller passes said arm the pressure of the hay in the compression-chamber causes immediate retraction of said plunger, thereby causing the arm 15 to again assume its nor mal position, as shown in full lines in Fig. 5, where it is properly. positioned to be impinged by the opposite roller 17 when it is advanced far enough in the rotation of the member 18, at which time the arm 15 is again advanced and the plunger is again forced inwardly, so that with each full rotation of the sweep the plunger is given two full strokes Depending from brackets 20 and pivotal-1y supported thereby are hangers 21, which are recessed, as shown,.for reception of the plate 22, which extends to the frame 23, in which are mounted the spindles 1619, before referred to. Opposite the recesses in said hangers are hollow lugs 24, in which are seated rods 25, the opposite ends of said rods being seated in hollow castings 26, which are bolted in position under the compressionchamber, whereby said rods 25 serve as braces for the hangers and through them to the plate 22. As the hangers are supported by means of bolts 27 passing through the plates 20, it is evident that said hangers may be removed when desired.

Mounted upon the frame of the compression-chamber and extending to a plane above the same is a standard 30, which is rigidly held in position by means of suitable securing 'means, and in proximity to said standard are hearings in which is rockably mounted a rela tively Y-shaped yoke, the bifurcated portion of-whichdepends with one arm at each side of themachine. Pivotally supported in the upper portion 31 of this yoke is a hay-packing member adapted. to assist the feed to the compression-chamber, and for convenience of description this member is called a fork 32, the upwardly-extending portion of which is pivoted as described and extends beyond. the pivotal portion upwardly, where a link 33 is connected, said link extending to and being pivotally mounted in the standard 30.

The arms 34 of the yoke pass downwardly at each side of the machine and are connected, by'means of the rods 35,with the arm 36, which is fast to the spindle 16. As the sweep 20 carries the member 18 with it, it also carries' with it the segmental gears 37 and 38, and when one of these-gear-sections comes into mesh. with the gear 39 the arm 36 will be carried in the direction indicated by the ar row 40, thereby drawing on the rods or cables 35, rocking the yoke 3134, and depressing the fork, which will pass into the compression-chamber of the machine. This last action takes place only after the plunger has been retracted, with a short interval of time to permit putting more hay into the compression-chamber and while the plunger is at its outermost position.

The plunger is provided at each side with rollers projecting laterally therefrom, as in dicated at 41 in Fig. 4, said rollers being carried. on short stub-shafts which project through slots 42 in the side walls of the ma chine, and when the plunger is forced into the compression-chamber these rollers impinge the legs 34. of the fork-carrying yoke, thereby quickly lifting said fork from the compression-chamber in advance of the arrival of the plunger.

In operation the draft-animals are connected with the sweep 20, which is caused to travel in the direction indicated by the arrow, and the member 18 is rotated, thereby causing the segmental gears 37 and 38 to alternately mesh with the gear 39 and causing the rollers 17 to alternately impinge the free end of the arm 15, thus alternately acting on the plunger-driving means and the fork-actuating means, with a slight intermission to permit filling the compression-chamber while the plunger is at the outer end of its stroke, and causing the plunger to be actuated twice for each full rotation of the sweep..

As it sometimes happens that the roller carried in the slot of the operating-lever is violently projected toward the upper end of the slot in said lever, there are provided abutment-blocks 415, which project into said slot, as shown in Figs. '1 and 2, which blocks are carried at the inner ends of the bolts 46, and'on said bolts are the springs 47, which bear on said blocks to normally force the said blocks into said slot, while nuts at the inner ends of the bolts are provided to retract the blocks when desired, said nuts bearing on the outer sides of the lever for this purpose.

It is evident that the plunger may be retracted by means of the segments 37 38 being brought into mesh with the gear 39, if desired, thus carrying the arm 36 in the direction of the arrow 40 and carrying the arm 16 back to its normal position when the segments and said gear are enmesh.
